Cracking of the surfacing bitumen on a bituminous roof or coating on a SPF roof, producing a pattern of cracks similar to an alligator’s hide. The cracks may not extend completely through the surfacing bitumen or coating. When left unattended, cracks and splits eventually develops. Water will enter the roofing system and cause unseen damage in the roof system. As the surfacing layer fails, the fiberglass reinforcement underneath is exposed and becomes brittle. Membrane failure inevitably follows.
Alligatoring is commonly found on smooth surface asphalt roofs. It is caused by the drying out of the exposed asphalt surfacing by the sun. When the defects are tiny, it's referred to as checking.
Smooth built up roofs should be inspected annually for damage. A roof coating may be applied to reflect harmful ultraviolet rays and reduce thermal cycling.
This roof repair procedure only applies to mild alligatoring on a built up roof. Areas with deep cracks will need too much product and you may be better off with other alternatives. Don't hesitate to call us for technical support. Advice is free, replacement is costly.
